No
The summary does not mention AI, ML, or any related concepts in the device description, intended use, or performance studies. The focus is on the hardware components and standard safety/performance testing.
Yes
The device is described as a "teletherapy device intended for the stereotactic irradiation of human head structures for adults," which indicates its use in treating a medical condition.
No
The device description indicates it is a teletherapy device for stereotactic irradiation, which is a treatment modality, not a diagnostic one. While it includes a kV x-ray system for positioning and verification, this is for aligning the treatment, not for diagnosing conditions.
No
The device description explicitly states it is a "medical teletherapy device" containing physical components like Cobalt-60 sources, a shield, collimators, and a kV x-ray system, indicating it is a hardware device with associated software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's a "teletherapy device intended for the stereotactic irradiation of human head structures." This describes a therapeutic device that delivers radiation for treatment, not a device used to examine specimens from the human body to provide information for diagnosis, monitoring, or treatment.
- Device Description: The description details a system with Cobalt-60 sources, collimators, and a positioning system. This is consistent with a radiation therapy device, not an IVD which would typically involve reagents, analyzers, or other components for testing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any processes associated with in vitro testing.
Therefore, based on the provided information, the Akesis Galaxy RTi Rotating Gamma System is a therapeutic device, not an IVD.

Summary of Performance Studies
Electrical Safety and Electromagnetic Compatibility (EMC) testing was conducted on this medical device. The system complies with the IEC 60601-1 standards for safety and the IEC 60601-1-2 standard for EMC. Successful testing was performed in accordance with IEC standards 60601-1-3, 60601-1-6, 60601-2-68, 60601-2-11, 60601-1-2, 61217, 62274 and 62366.
Hardware and software verification and validation testing was conducted according to the FDA Quality System Regulation (21 CFR §820), ISO 13485 Quality Management System standard, ISO 14971 Risk Management Standard and the other FDA recognized consensus standards. Test results showed conformance to applicable requirements specifications and assured hazard safeguards functioned properly. Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software in Medical Devices." The software for this device was considered as a "major" level of concern.
Biocompatibility testing was not performed since this device does not have any direct tissue contacting components / parts.

Dear Mr. Brown:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmp/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see
